REFERENCE MANUAL
HomeRF
An industry standard that combines 802.11b and portable phone standards for home networking. It uses frequency hopping (switching of
radio frequencies within a given bandwidth to reduce the risk of unauthorized signal interception). HomeRF offers data transmission speeds of
up to 1.6 Mbps at distances of up to 150 feet.
Host name
The DNS name of a device on a network, used to simplify the process of locating computers on a network.
Hub
A device that has multiple ports and that serves as a central connection point for communication lines from all devices on a network. When
data arrives at one port, it is copied to the other ports.
IEEE
Acronym for ‘Institute of Electrical and Electronics Engineers’. A society of engineering and electronics professionals that develops standards
for the electrical, electronics, computer engineering, and science-related industries. The IEEE (Eye-triple-E) is a non-profit, technical
professional association of more than 377,000 individual members in 150 countries. The full name is the Institute of Electrical and Electronics
Engineers, Inc., although the organization is most popularly known and referred to by the letters I-E-E-E.
Infrastructure network
A network configuration in which wireless devices connect to a wireless access point (such as GlobeSurfer
®
II) instead of connecting to each
other directly.
Internet domain
In a networked computer environment, a collection of computers that share a common domain database and security policy. A domain is
administered as a unit with common rules and procedures, and each domain has a unique name.
Intranet
A network within an organization that uses Internet technologies (such a Web browser for viewing information) and protocols (such as TCP/IP),
but is available only to certain people, such as employees of a company. Also called a private network. Some intranets offer access to the
Internet, but such connections are directed through a Firewall.
IP
Acronym for ‘Internet Protocol’. The protocol within TCP/IP that is used to send data between computers over the Internet. More specifically,
this protocol governs the routing of data messages, which are transmitted in smaller components called packets.
IP address
Acronym for ‘Internet Protocol’ address. IP is the protocol within TCP/IP that is used to send data between computers over the Internet. An
IP address is an assigned number used to identify a computer that is connected to a network through TCP/IP. An IP address consists of four
numbers (each of which can be no greater than 255) separated by periods, such as 192.168.1.1.
ISO/OSI
Reference model Abbreviation for International Organization for Standardization Open Systems Interconnection reference model. An
architecture that standardizes levels of service and types of interaction for computers that exchange information through a communications
network. The ISO/OSI reference model separates computer-to-computer communications into seven protocol layers, or levels; each builds on
and relies on the standards contained in the levels below it. The lowest of the seven layers deals solely with hardware links; the highest deals
with software interactions at the program level. It is a fundamental blueprint designed to help guide the creation of hardware and software for
networks.
ISP
Acronym for ‘Internet service provider’. A company that provides individuals or companies access to the Internet.
Kbps
Abbreviation of ‘kilobits per second’. Data transfer speed, as through a modem or on a network, measured in multiples of 1,000 bits per
second.
LAN
Acronym for ‘local area network’. A group of computers and other devices dispersed over a relatively limited area (for example, a building) and
connected by a communications link that enables any device to interact with any other on the network.
MAC address
Abbreviation for ‘media access control’ address. The address that is used for communication between network adapters on the same subnet.
